SportLegs jump-starts your muscles’ natural chemistry to make less lactic acid in the first place. It replicates the signal muscles obey to curb the excess lactate production that forms lactic acid.

Since the 1970s, modern atomic research tools have let scientists see how lactate, an organic metabolite found throughout the body, functions as “energy currency” to optimize fuel distribution throughout our complex network of muscles. Radioactive isotope tracers let scientists watch how muscles produce, consume and exchange lactate to power exercise. Lactate’s primary benefit is its speed, facilitating energy exchange directly between working muscles without circulatory plumbing, distributing muscle energy through tissue and even cell membranes without delay. Further research showed lactate’s magic is effective only within a narrow range of pH; if it becomes acidic, its instantaneous trans-membrane perfusion speed slows drastically. When this “Lactic Acid” occurs, athletic performance decreases, with attendant muscle “burn” and post-exercise soreness.

Continuing research suggested lactate becomes acidic as it pools in muscles, after muscles produce more than they can promptly consume, as typically occurs early in exercise. Studies since 1975 have shown muscles stop producing excess lactate in response to rising lactate concentration in the bloodstream. We theorized lactate supplementation before exercise could replicate this signal in time to prevent the oversupply situation in the first place. Our experiments beginning in 1989 showed pre-exercise supplementation was indeed effective, noticeably inhibiting formation of lactic acid, and preserving ideal pH environment to optimize the Lactate System’s energy contribution.

Once people try SportLegs, they want to keep it to themselves. We’re grateful to those who choose to spread the word.

5 stars Yeah, they work for me

I was skeptical but the science seemed reasonable: Preload lactate so your muscles produce less. Whatever. I'm a believer. Finished first bottle and reordered. Going with dosage on label: 1 cap per 50 lbs. body weight. These work so well for me that I hesitated about writing a review and there's no way I'm telling my riding buddies...

We apologize for running out. International customers have discovered SportLegs, and they bought all we had for ski season. In the meantime, 5-capsule single-dose packets are available on this site for $2.49 each.
